Arterial Blood Gas Analysis and Clinical Interpretation

Interpreting arterial blood gas results quickly and accurately is an essential skill across critical care, anesthesia, and cardiopulmonary monitoring. This text-based course guides you through the core principles of blood gas analysis, helping you demystify complex lab values and translate them into actionable clinical understanding. You will build a reliable, step-by-step framework to evaluate respiratory and metabolic disturbances, assess oxygenation status, and recognize compensatory physiological mechanisms. What you will learn: - Understand core physiological concepts, standard reference ranges, and key terminology including pH, PaCO2, PaO2, and HCO3 - Identify primary acid-base disorders including metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis - Calculate and evaluate the anion gap and delta ratio to detect mixed disorders - Apply base excess and modern quantitative acid-base evaluation principles to clinical interpretation - Assess oxygenation indices, alveolar-arterial gradients, and tissue perfusion markers like blood lactate - Practice systematic analysis on realistic written case scenarios across acute and perioperative care settings The course begins with foundational acid-base chemistry and essential parameters before progressing through systematic interpretation frameworks and realistic patient cases. This course is designed for healthcare students, nurses, perfusionists, and clinicians seeking a structured, beginner-friendly approach to blood gas interpretation without prior advanced training required.
